如何在fedora上关闭ipv6

有时因为某些服务器不支持ipv6会出现EHOSTUNREACH错误，需要关闭ipv6

1. 将如下几行配置添加到 /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

2. 重新加载以上配置

sysctl -p

3. Check. A ‘1’ means IPv6 has been disabled

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
